Volvo Penta AQ-Series Thermostat 875580

82°C / 180°F | B21 / B23 / B230 Petrol Engines

Aftermarket 82°C thermostat kit for selected Volvo Penta four-cylinder petrol sterndrive and inboard engines based on B21, B23 and B230 engine families and using reference 875580.

FITMENT CHECK: This is a high-temperature 82°C application. It must not replace a lower-temperature thermostat specified for raw-water-cooled engines merely because the housing looks similar.
